Potential Yocto Project 1.1 Features
Yocto Project 1.1 - Target release = October 2011
Yocto Project 1.1 Themes
The topics below are the themes that some members of the team have started brainstorming for Yocto Project 2011.10. These will grow and change with community input.
Yocto Project 1.1 Objectives
The objectives of the Yocto 1.1 release are to grow participation in Yocto and increase the number of BSPs written for Yocto and partner products based on Yocto.
Yocto Project 1.1 Theme List
The Yocto Project 1.1 Themes towards the Objectives listed above are:
- Multilibs & OE-core config - This work, which began in Yocto Project 1.0, needs to be completed.
- Improve ease of BSP creation - Document the lifecycle and process. Possibly create walkthroughs or tutorials to integrate a new board into the linux-yocto kernel.
- Enable users to easily and seamlessly build Yocto images - This refers to the effort to complete and integrate the Image Creator work started in 1.0.
- Build performance – Get to the goal of 1 hour build time on a developer machine.
- Upstreaming – Submit patches to upstream projects in order to reduce the large number of patches which are currently part of Yocto Project.
Process for Entering New Feature Requests

BSPs
| Feature Name | Description | Priority | Status | Source | Comments / Bugzilla Links |
| Support for AVX as in kernel 2.6.30. - Already in 1.0 | Any toolchain support needed? | 1 | Review | Jay | M1; Owner = Nitin |
| Optimize support for Intel hardware features | We need to understand and track each important Intel hardware feature and how it should be optimally supported in the Intel BSPS. Items that immediately come to mind are power, video, and performance counter settings, etc. | 1 | Review | Tom | Owner: Tom/Darren |
| Fish River Island/Fish River Island II BSP(s) | The base Fish River Island BSP exists already, we now need to add support for the extra devices, and add support for changes introduced by Fish River Island II | 2 | Review | Tom | Owner: Tom |
| Support ECG (ongoing) | ECG is ramping up with Yocto BSPs and likely will require significant amounts of time and help. Also, since we're trading their BSP work for our help in upstreaming patches, we're also likely to have to spend a significant amount of time with upstream-related tasks too. | 1 | Review | Tom | Owner: Tom |
| Additional config options | The following configurations need to be enabled to support DPDK:

1 | Review | Rahul | Owner: Tom ? |
| BSP update/intro | determine and integrate / create arch reference BSPs (e500, Cortex, ARM, MIPs) | 2 | Accept | Bruce/Richard/team | Owner: Bruce, M2, 4th Sprint |
ADT
| Feature Name | Description | Priority | Status | Source | Comments / Bugzilla Links |
| More test cases about toolchain in autobuilder | 2 | Review | ADT Team | Owner = Jessica | |
| Eclipse-native tools interface | More integrated with upstream once there's integrated Linux tools that meets our need, e.g. lttng-remote | 2 | Review | ADT Team | Owner = Jessica |
| Indigo update | Update to the latest Eclipse release (Indigo) | 2 | Review | ADT Team | M2; Owner = Jessica |
| Changes for Image Creator | Eclipse changes pending Image Creator | 1 | Review | ADT Team | M2; Owner = Jessica |
| Secure login | 2 | Review | ADT Team | Owner = Jessica | |
| Prebuit SDK integration | speedup target image generation by reusing prebuilt tools from SDK native and target binaries. See: http://wiki.secretlab.ca/Yocto_prebuilt_SDK_integration | 2 | Deline | Adrian | This functionality looks to have been provided by sstate packages? Owner = Jessica |
| Systemtap integration | Make it easy and convenient for the user to write and execute Systemtap scripts from the IDE. http://www.eclipse.org/linuxtools/projectPages/systemtap/ might provide a good starting point and may be something we can contribute to. We may also need to contribute further up the chain to provide e.g. remote target capabilities. | 2 | Review | Tom | Owner = Jessica |
| 'perf scripting' integration | Make it easy and convenient for the user to write and execute 'perf scripts' from the IDE. We should be able to leverage and build on the Systemtap integration for this. | 2 | Review | Tom | Owner = Jessica |
| Enhance the deploy part in remote debug | ADT is currently using org.eclipse.cdt.remote.launch for remote debug. One limitation in this plug-in is that it can only deploy one single file to the target during the debug. Though it is ok for debugging static linked program, debugging dynamic linked program might require deploying multiple files(including executables and libraries) to the target. | 2 | Review | Lianhao | Owner = Jessica |
Documentation
| Feature Name | Description | Priority | Status | Source | Comments / Bugzilla Links |
| Package Documentation Audit | Make changes defined in the package documentation audit from Yocto 1.0 | 2 | Review | from 1.0 | Owner = Saul |
| Yocto Project Development Guide | This manual would be an over-arching document that frames the complete development cycle within Yocto Project. The idea here is that the document would be an umbrella document that spawned and referenced subsequent documents. The organization would be the first chapter overviews the major development pieces such as recipe creation, building, debugging, publishing, fail-safing, back-door hook creation, etc. This manual will also include migration information. Scoping would be about two weeks and length would probably be about 40 pages. Overall development time will likely take up to the release given my experience on the creation of the ADT manual (there is no uniterruped time). | 1 | Not Started | from scratch | M4 (final) Owner = ScottR |
| Various Demo Videos | The idea here is to create screen-capture type tutorials similar to what exists for the ADT Eclipse Plug-in. However, we want to contract out some help for professional voice-over talent to be used with the images. These don't have to be limited to screen-capture material but could include well-done PPT decks - similar to how other business units in Intel create various training modules. For 1.1 it would be good to capture the script for the existing ADT Eclipse Plug-in module and have it voiced over. Also, for 1.1 it would be good to create a similar module for the Image Creator application. | 2 | Not Started | From ADT module and scratch | M2 Owner = ScottR |
| Open-source Newbie Information | This information will be for developers new to open-source. These people do not know what IRC means. Targeted for developers coming from a non-open-source environment. I think the best place for this information would be the website. I haven't looked yet but I suspect information already exists on the web. For Yocto it will be a matter of collecting the best and most useful information, orginizing it and properly referencing/leveraging it. | 2 | Not Started | From scratch | M4 (final) Owner = ScottR |
| Tarball Doc process | Right now tarball docs are frozen shortly before a release. The tarball never gets updated beyond that during subsequent documentation development. However, website docs are periodically updated as changes are made during the next development cycle. We need a documentation process where the tarball docs are updated along with the website docs. Perhaps releasing and building a separate documentation tarball is an answer... This whole scheme needs thought about and something implemented. | 3 | Not Started | From scratch | M3 Owner = ScottR |
| OOB documentation | Create an out of box guide for giveaway systems built using Yocto. | 1 | Review | Julie | M? Owner = ScottR |
| Tracing/profiling HOWTOs | Create a document or extend the current Yocto tracing wiki page to explain in detail how to use all the tracing tools in Yocto. It should detail not only how to use each tool individually, but also how to use them in conjunction with each other, highlighting situations in which each is most useful. There should also be some extensive worked examples of real-life use-cases and how they could be investigated using the Yocto tracing/profiling tools. | 2 | Review | Tom |
Build
This section contains requirements related to the build (autobuilder activities, performance, footprint, etc.)
| Feature Name | Description | Priority | Status | Source | Comments / Bugzilla Links |
| Autobuilder maintenance | Bring scripts into configuration or get git repo working for those that can't be brought in. (takes 2 days) | 1 | Review | Beth | M1; Owner = Beth |
| Meta targets | Part of the challenge of autobuilder is that you have to go into autobuilder, edit script, reconfigure, to change just one build target. This is error prone. What we need is a meta-target where Beth can say she wants to build Poky-image-sato for QEMU x86 and have it just do that. Beth thinks this is done via an override to the web page. (takes ~2 weeks) | 1 | Review | Beth | M2; Owner = Beth |
| License tracking | Get common licenses for all packages and consolidate base file licenses. (takes ~3 days) | 1 | Review | Beth | M1; Owner = Beth |
| License tracking | Build a parser to do license tracking more gracefully and make sure all recipes are correct. (takes ~2 weeks) | 1 | Review | Beth | M2; Owner = Beth |
| Audotbuilder infrastructure | Bring up additional autobuilders and work with sysadmin to configure. | 1 | Review | Beth | M2; Owner = Beth |
| Overall Project | Host a retrospective to discuss what went well and what can be improved in Yocto 1.0. (questions on this?) | 1 | Review | Beth | M1; Owner = Beth |
| Release Scripts | Create Release Scripts that can be used for both a weekly release and for OCT 2011 release to be run by autobuilder (a week. testing on this may take longer) | 1 | Review | Beth | M3; Owner = Beth |
| Enhanced Performance | Also, environmental requirements/suggestions for expected performance; Goal is to build in under 1 hour | 1 | Review | from 1.0 | |
| Disk Space Reduction | 2 | Review | Team | Owner = TBD - WR distro team might be willing to own if they know what is required | |
| Share gcc work directories | 2 | Review | Team | Owner = TBD - WR distro team might be willing to own if they know what is required | |
| Patch Test System | Create a machine where developers can upload/test patches before submitting them to master to ensure builds won't break when patches are added. (developer autobuilders? Fuzz builds?) | 2 | Review | Team | |
| build statistics reporting | As someone interested in how long it takes to build different images on different hardware configurations and other assorted build metrics, I would like a web based service, that takes output generated by an extended buildstats.bbclass and stores it, to compare against different machines. The end result should be a way to visualize the collected data. See: https://wiki.yoctoproject.org/wiki/Yocto_Buildbot_Autobuilder_Discussions | Review | eflanagan/Jay7/ka6sox | ||
| BSP builds | Autobuilder git fetcher improvements (3 days) | 2 | Review | from 1.0 | M1; Owner = Beth |
| Implement Continuous Autobuilds | Build constantly instead of daily (need fuzz builds for this. once fuzz builds are implemented, this is trivial) | 2 | Review | from 1.0 | M1; Owner = Beth |
Performance and Usability
This section contains general Yocto performance as well as usability items.
| Feature Name | Description | Priority | Status | Source | Comments / Bugzilla Links |
| Fast boot time | 2 second boot time target | 1 | Review | Team | M2; Owner = Darren |
| Build Yocto behind firewall | Darren will investigate site.conf and documentation | 2 | Review | Dave | |
| Minimal Image unique | make minimal image smaller | 3 | Review | Team | M2; Owner: WR Distro Team |
| POSIX support | address POSIX failures found in 1.1 | 2 | Review | Team |
Kernel
This section contains items specific to the Yocto kernel.
| Feature Name | Description | Priority | Status | Source | Comments / Bugzilla Links |
| BSP kernel config audit | Audit kernel configs for the various BSPS. Should not be limited to just kernel config options -- it should also include discussion of overall strategies for defining and managing base branches, feature topic branches, config features, etc, and should result in not only the current kernels being changed to match, but also BKMs being published somewhere, probably in the kernel manual. | 1 | Accept | Team | Owner = Bruce, M1, 4th Sprint |
| Kernel Tools | Figure out plan for kernel tools (are they merged into main repo or their own project?) | 1 | Accept | Bruce/Mark | Owner = Bruce, M1, 3rd Sprint |
| Kernel Tools | Implement plan for kernel tools | 1 | Accept | Bruce/Mark | Owner = Bruce, M1, 4th Sprint |
| Kernel Build | auto yoctization. allow the building of arbitrary repos and kernel versions via the yocto kernel meta data | 1 | Accept | Bruce | Owner = Bruce, M1, 2nd Sprint |
| Kernel Update | kernel dev/next repo created. feature merges (fs, boot, tiny, controllers, etc). reference tree merges (omap, davinci, etc) | 1 | Accept | Bruce | Owner = Bruce, M1, 3rd Sprint |
| Kernel Version | Confirm kernel version | 1 | Accept | Bruce | Owner = Bruce, 6 weeks before dev done |
| BSP config cleanup | BSP config cleanup/refactoring. Update to new kernel rev. Investigate Kconfig alignment | 1 | Accept | Bruce | Owner = Bruce, M2, 4th Sprint |
| inter-core comms | investigate/report/merge intercore communication methods (mcapi, dsplink,etc). extend as appropriate | 2 | Accept | Bruce | Owner = Bruce, M2, 1st Sprint |
| use cases | BSP config streamlining, building the kernel standalone, yoctoization, meta data sharing | 1 | Accept | Bruce | Owner = Bruce, M3, 1st Sprint |
| Ongoing kernel maintenance | There should be a task spread out over the whole release, say 10% of one person's time (just a guess), for monitoring LKML and Linus' master branch, and/or relevant lists for patches relevant to the BSPs we maintain. We also need to figure out if Bruce needs help with the management of the base branches e.g. re-enabling features after kernel uprevs, moving feature tags forward, etc. | 1 | Review | Tom | Owner = Bruce, M2 4th Sprint |
| Tracing: perf trace scripting support | Basically this means allowing perf to be built with the Perl and Python bindings, which turned out to be a headache last time. | 2 | Review | from 1.0 | Owner = Tom |
| Tracing: Add Systemtap support for userspace tracing | Add utrace, etc | 2 | Review | Tom | Owner = Tom |
| Tracing: Systemtap usability in Yocto | Right now, there are instructions on the wiki on how to configure and use Systemtap with Yocto. While straightforward, they are tedious and unlikely to be useful to most people pressed for time. We need to make it easier to use - in addition to documentation/HOWTO tasks listed elsewhere on this page, we need to make it usable 'out of the box' (i.e. outside of ADT) e.g. all paths and configuration handled via script or something similar | 2 | Review | Tom | Owner = Tom |
| Tracing: tuna, oscilloscope recipes | catch up with Tom, likely to remove | 3 | Review | from 1.0 | will be removed |
